ELEVATOR-BUCKET.

Specification of Letters Patent.

Patented Sept. 17, 1912.

Application filed April 20, 1911. Serial No. 622,410.

To all whom it may concern:

Be it known that I, FRANK G. LAWYER, a citizen of the United States,residing at Iola, in the county of Allen and State of Kansas, haveinvented certain new and useful Improvements in Elevator-Buckets, ofwhich the following is a specification, reference being had therein tothe accompany-- ing drawing.

This invention relates to elevator buckets, and the principal object ofthe same is to produce a bucket so constructed that dirt or othersubstance carried by the bucket will very readily drop out when thebucket is inverted.

Another object of the invention is to provide a bucket which is formedfrom a single piece of material and to so shape the blank from which thebucket is made that when the bucket is completely formed the ends of thesame will be of double thickness, thus giving the portion of the bucketwhich receives the most strain a reinforcement.

This invention is illustrated in the accompanying drawings, whereinFigure 1 is a perspective view of the improved bucket. Fig. 2 is a viewin transverse section through the bucket. Fig. 3 is a view inlongitudinal section through the bucket. Fig. i is a view of the blankfrom which the bucket is made.

This bucket is rectangular in shape and has a rear wall 1, a front wall2, a curved bottom 3 and double end walls 4 and 5.

This bucket is formed from a blank which comprises a rectangular bodyportion provided with transversely extending creases 6 and 7 whichdivide the body portion so that it can be folded to form the rear wall1, the bottom 3 and front wall 2. Reinforcing tongues 8 and 9 extendfrom each end of the central portion of the blank which forms the bottom3 and are used to brace the bot tom portions of the end walls as will behereinafter brought out. Similarly construct-ed wings 10-10 and 1111extend from each end of the rear wall 1 and the front wall :2. Each ofthe wings 10 has a sloping edge 12 which forms the upper edge of the endwall and a second sloping edge 13 which forms the front edge of the endwall. A curved edge 14 is formed so as to cause the bottom of the bucketto be curved. Each of the wings 11 has a straight edge 15 which formsthe upper edge of the second section of the end wall and a sloping edge16 which rests against the rear wall of the bucket. The w1ng1s alsoprovided with a curved edge 17 so as to conform to the curvature of thebot tom of the bucket. Each of the wings is provided with openings 18positioned adjacent the edges and with centrally located openmgs 19.These openings are so positioned that when the blank is folded to formthe bucket the openings in the wings will register.

In forming this bucket the blank is folded along the creases 20 and 21and is then folded along the creases 6 and 7 so that the wings 11 willbe brought within the wings 10 and tongues 8 and 9 and against the rearwall 1. Rivets 22 are passed through the openings 18 and hold the bucketin the set up position. If desired bail cars can be secured to the endwalls by passing rivets through the openings 19 or if desired hooks maybe secured in the openings. The tongues 8 and 9 brace the bottom andlower portions of the end walls and the double end walls give the bucketa great deal more strength as the principal part of the strain comesupon the end walls.

When emptying this bucket it is tipped forwardly and the contents of thebucket empties very easily as the sloping front wall 2 causes as smallamount of resistance as possible, and the curved bottom prevents anydanger of the contents sticking in the corners as would be the case if asharp corner were formed at the junction of the front and rear wallswith the bottom.

What I claim as my invention is z- 1. A bucket formed from a singleblank, said blank comprising a main body portion constituting whenfolded the bottom and two sides of the bucket, those portions of thebody constituting the sides provided at their opposite edgesrespectively with similarly shaped wings, said wings being of a widthand height substantially equal to the width and height of the finishedbucket, said wings overlapping to form end walls of double thicknessthroughout substantially the entire area of the ends of the bucket andsaid wings having registering openings at their opposite edges, andfastening means passing through said registering openings.

2. A bucket formed from a single blank, said blank comprisinga main bodyportion constituting when folded the bottom and two sides of the bucket,those portions of the body constituting the sides provided at theiropposite edges respectively with similarly shaped wings, said wingsbem'g'of a width and height substantiallyequal to the width and heightof the finished bucket,

said wings overlapping to form end'walls openings, that portion of'thbody of the blank constituting the bottom of the bucket havingrelatively narrow tongues folded about the lower edges of theoverlapping wings at the ends of the bucket. 7

In testimony whereof I hereunto aflix my signature in presence of twowitnesses.
